Micronutrients & recovery

Dietary magnesium intake below the Recommended Daily Allowance (RDA) is associated with significantly higher levels of C-reactive protein (CRP), a marker of inflammation and cardiovascular risk, in US adults not taking magnesium supplements.

Check your magnesium intake. If you are over 40 or overweight, ensuring you meet the Recommended Daily Allowance (approx. 310-420mg/day depending on age/sex) through diet (leafy greens, nuts, legumes) may help lower inflammation markers like CRP. Since most people fall short, prioritizing magnesium-rich foods is a low-risk strategy for cardiovascular health.

After controlling for demographic and cardiovascular risk factors, adults who consumed <50% RDA of magnesium were 2.24 times more likely to have elevated CRP (95% CI 1.13– 4.46) than adults ≥RDA.
